In a large factory in Hebei, workers store 6-meter-long steel plates on drawer-type sheet metal shelves. The shelves feature a multi-layer drawer storage structure, with each layer supporting up to 5 tons. Designed for hand-crank operation, they are typically hoisted onto racks with forklifts or cranes. A set of shelves can accommodate 5-8 drawer levels, offering storage capacity of approximately 20-40 tons.
